It's quite possible that this plugin will not play nice with other plugins that modify Wordpress' revisioning. I've had no problem with GD Press Tools, but other than that I don't know. Please report any conflicts to me. I'll list incompatible plugins here.
The best place to leave comments or issues is at the plugin site: http://www.kingrat.us/plugins/published-revisions-only I do not monitor the Wordpress.org support forums, so any problems left there are likely to have untimely responses.
